The specific embodiment
For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
The utility model provides a kind of molten resin legal system for preimpregnation yarn system, comprise that fibre bundle is wrapped on silvalin cylinder for placing the creel 1 of silvalin cylinder, fibre bundle enters heating drying tunnel 2 after being drawn by creel 1, in heating drying tunnel 2, to fibre bundle, heat, make fibre bundle surface slurry softening.Fibre bundle is directed to exhibition yarn feeding device 4 by guide roller 3-1 after going out to heat drying tunnel 2.
In conjunction with Fig. 2, exhibition yarn feeding device 4 is comprised of a swing arm 15, a vibration rod 16 and a fixed bar 17.Swing arm 15 swing in the direction perpendicular to the fibre bundle direction of motion (as shown in the direction of arrow in Fig. 2), vibration rod 16 moves up and down (as shown in the direction of arrow in Fig. 2) in the direction perpendicular to fibre bundle plane of movement, and fixed bar 17 maintains static.Can regulate respectively the hunting frequency of swing arm 15 and vibration frequency and the vibration amplitude of amplitude of fluctuation and vibration rod 16 by two adjustable micromachines of speed.Due to the side-to-side movement of swing arm 15 and moving up and down of vibration rod 16, therefore to fibre bundle applied pressure, can be decomposed into two component of horizontal direction and vertical direction, make fibre bundle in vertical plane, be subject to all the time before and after and the effect of upper and lower two pairs of pulling force, like this fibre bundle certainty be widened, attenuation.
Widen, the fibre bundle after attenuation is directed to glue spreading apparatus by guide roller 3-2.In conjunction with Fig. 3, glue spreading apparatus comprises a pair of glue feeding roller 7 and has the glue spreader 6 of smooth surface, and the smooth surface of glue spreader 6 can obtain by the mode of polishing.Glue feeding roller 7 and glue spreader 6 form gap respectively and between spreading knife 8.Thereby the resin in molten condition forms resin glued membrane by the gap feeding between glue feeding roller 7 and spreading knife 8 on the surface of glue feeding roller 7, and the gap between glue feeding roller 7 and spreading knife 8 is adjustable, adjusts the flow of resin by adjusting this gap.Fibre bundle is gone out by the gap between glue spreader 6 and spreading knife 8 after being entered by the gap between glue feeding roller 7 and glue spreader 6 again.Acting in conjunction by glue feeding roller 7 and glue spreader 6 is coated with resin the fiber surface that is pressed in fibre bundle, and fibre bundle is scraped off the unnecessary resin in fibre bundle surface by it during by spreading knife 8.Gap between glue spreader 6 and spreading knife 8 is adjustable by positioning bar 18, by adjusting this gap, adjusts the content of resin in the final preimpregnation yarn forming.
The fibre bundle that painting is pressed with resin goes out glue spreading apparatus by being directed to hot-press arrangement by guide roller 3-3.Hot-press arrangement adopts three groups of hot-pressing rollers, is respectively hot-pressing roller 9, hot-pressing roller 10, hot-pressing roller 11, adopts the method for pressing step by step that the fibre bundle and the resin that flatten are evenly combined.Hot-pressing roller 9, hot-pressing roller 10, hot-pressing roller 11 surfaces keep certain temperature, make resin at this temperature, have lower viscosity, in viscous state, are convenient to impregnation of fibers.
Fibre bundle goes out hot-press arrangement and is directed to cooling device via guide roller 3-4.In conjunction with Fig. 4, cooling device comprises the reeded chill roll 12 of surface band, and the width of groove adapts with the fibre bundle width being imported into, and fibre bundle is directed in this groove.By chill roll 12, the chilling temperature of fibre bundle is controlled to-20 ℃～30 ℃.Chill roll 12 adopts metals to make, and scribbles one deck prevent that (English is: Teflon) coating for the Teflon of described fibre bundle bonding chill roll 12 on its surface.
